Events

• onTrigger

  This event is triggered when the user performs an operation as defined by the triggerMode property. The parameter passed to the event handler is the error status. The error status returns the following values:

  triggerMode	status value	Description
  read	< 0	Failure
  >= 0	Success
  write	< 0	Failure
  >= 0	Success
  kill	< 0	Failure
  >= 0	Success

  When you want to obtain the received RFID data you can do this inside the event handler function from the passed Event parameter. An example of how you can do this is shown below.

  String status = (String) wdEvent.getParameters().get("status");
